High power single-frequency continuous-wave Nd:YVO4 master-oscillator power amplifier
High power single-frequency continuous-wave Nd:YVO4 master-oscillator power amplifier
We report a highly-efficient, high-power, single-frequency Nd:YVO4 master-oscillator power-amplifier with near-diffraction-limited output beam quality. A diode-pumped Nd:YVO4
ring laser incorporating a passive method for suppressing
axial-mode-hopping was employed as the master-oscillator, and was
amplified by a three-stage diode-end-pumped Nd:YVO4
amplifier, yielding 79 W of output with an extraction efficiency of 29%.
The overall power gain was 15 dB for an input power from the
master-oscillator of 2.4 W, and the M2 parameter was less
than 1.5 at the maximum power. The prospects for a further increase of
power and brightness via this approach are considered.

Abstract
We report a highly-efficient, high-power, single-frequency Nd:YVO4 master-oscillator power-amplifier with near-diffraction-limited output beam quality. A diode-pumped Nd:YVO4
ring laser incorporating a passive method for suppressing
axial-mode-hopping was employed as the master-oscillator, and was
amplified by a three-stage diode-end-pumped Nd:YVO4
amplifier, yielding 79 W of output with an extraction efficiency of 29%.
The overall power gain was 15 dB for an input power from the
master-oscillator of 2.4 W, and the M2 parameter was less
than 1.5 at the maximum power. The prospects for a further increase of
power and brightness via this approach are considered.
